Table 4 Comparing StoreOnce Catalyst, NAS and Virtual Tape device types Device Type Key Features Best Used In Comments Virtual Tape (VTL) Uses virtual tape drives and virtual slots to emulate physical tape libraries Enterprise FC SAN environment (some models do not support FC). HP StoreOnce also supports iSCSI VTL (not B6200) Tried and tested, well understood with traditional backup applications Uses Robot and Drives device type NAS (CIFS/NFS shares) NAS shares can be easily configured and viewed by the operating system: CIFS shares for Windows, NFS shares for Unix Specific environments that This is a NAS target for do not support tape backup - not recommended emulation backup or prefer for random NAS file type to backup directly to disk. In access. nl some cases the licensing Uses Basic Disk device type may be lower cost for NAS shares as a backup target. Consider this device type for virtualized environments StoreOnce Catalyst (stores) Backup software has total control over the HP StoreOnce appliance, providing source-based deduplication, replication control, improved DR etc. Environments that require a single management console for all backup and replication activities and the ability to implement federated deduplication* nl Wherever possible HP recommend the use of HP StoreOnce Catalyst May require additional plug-in components on Media Servers nl Uses OpenStorage device type (Symantec) or Backup to Disk ( HP Data Protector) device type * Federated deduplication is an HP term referring to the ability to distribute the deduplication load across Media servers. This feature is sometimes known as source-based deduplication or low bandwidth backup. Networking and Fibre Channel considerations NOTE: See Networking considerations and Fibre Channel considerations for more information about Ethernet and FC configurations and best practices. The following table shows which network and fibre channel ports are present on each model of StoreOnce appliance. Correct configuration of these interfaces is important for optimal data transfer. A mixture of iSCSI and FC port virtual libraries and NAS shares can be configured on the same StoreOnce appliance to balance performance needs if required. • The HP StoreOnce B6200 Backup system does not support iSCSI virtual libraries. • The HP StoreOnce 2700, 2620 and 4210 iSCSI Backup systems do not support FC virtual libraries.
